摘　　要：提出一种基于假设检验的软件可靠性模型预测精度比较方法,该方法将模型预测值与真实值的RE(相对误差)看作随机变量,利用假设检验思想度量模型预测精度,并给出多个模型之间预测精度的比较标准.This paper investigates the method to compare the forecast accuracy of software reliability models based on the hypothesis test. Regarding the RE between the values of forecast and verity as the random (variable,) this method gives the comparing criterion among software reliability models.

关 键 词：软件可靠性模型 预测精度 假设检验
